Pretty sure it doesn't have any dealer-added aftermarket suspension upgrade. Just checked the window sticker, no KDSS listed. I know on the driver's side on the KDSS-equipped models, there is a big skid plate with a cylinder underneath and that is where you have to watch about snow/ice/salt/mud getting packed in and rusting it out. You can clean it by removing the skid plate. Well mine doesn't have this.
I get a bit lost when people start talking about struts and sway bars and the like, but in looking at pictures of the underside of the KDSS ones, mine is different. No vertical piston in an accordion boot, just some horizontal accordion boots.
